SMLSCO cast elbow series offers multiple forms to meet different pipeline layout requirements. This 45° elbow is used to achieve a smooth turn in pipelines, and can generate less fluid resistance compared to a 90° elbow. In addition, we also offer 90° elbows for standard right angle turns, as well as Street Elbows with internal and external threads on one end to save installation space, to meet your diverse connection needs.

This elbow is connected with NPT (American standard pipe taper thread), with a tooth angle of 60° and a thread taper of 1:16, which can form an effective mechanical seal when tightened. This connection method does not require welding, and installation and disassembly are very convenient. It is one of the most common connection forms in industrial and civilian pipelines in North America and globally, and is highly cost-effective and flexible.

304 stainless steel (cast as CF8) is the most widely used and cost-effective stainless steel grade. It exhibits good corrosion resistance in water, air, and various weakly corrosive media, effectively preventing rust and ensuring the cleanliness of fluid media. Its excellent mechanical properties and ease of processing make it an ideal material for manufacturing low-pressure pipe fittings in fields such as water supply and drainage, general chemical engineering, etc. It combines reliability and economy.

The Class 150 cast 45° elbow is mainly used for achieving smooth turning in low-pressure pipelines. They are widely used in building water supply and drainage, HVAC, and general industrial fluid transport systems to bypass obstacles or construct complex pipelines with lower flow resistance. Its convenient threaded connection method and economy make it a common choice for achieving flexibility in pipeline layout under non critical and non high pressure conditions.
